S.M.A.R.T. (Self-Monitoring, Analysis,
and Reporting Technology) Technology
co-developed by HP and the hard drive
industry that provides warning of imminent
drive failure. This feature makes it possible
for HP to offer Pre-Failure Warranty
replacement of hard drives. S.M.A.R.T.
supersedes the drive parameter tracking
feature that was previously used for this
purpose because the self-monitoring routines
used in S.M.A.R.T. are more accurate than
the drive parameter tracking tests. The
self-monitoring routines are customized for
that specific drive type and have direct
access to internal performance, calibration,
and error measurements.
SNMP (Simple Network Management
Protocol) Governs network management
and the monitoring of network devices and
functions.

Interconnect) A type of external SCSI
connector used by Ultra SCSI controllers.
